Description:

[0001]The present invention relates to a method of defacing, such as
marking or staining, and/or destroying items stored in an alarmed value
space according to the preamble of claim 1. The invention also relates to
an arrangement and to a use.

[0002]In respect of spaces for storage of valuables, for instance
banknotes, cheques and other types of items there is a need of rendering
such items useless when an attempt is made to break into the space
unlawfully.

[0003]WO 99/61741 and WO 03/089745 exemplify earlier known methods and
arrangements in the aforesaid technical field.

[0004]These earlier publications describe the distribution of a document
defacing agent/document destruction agent whose activation is dependent
on the force of gravity to a great extent. This means that a user is
dependent on maintaining the orientation of the document accommodating
space in order to obtain an optimum defacing effect/destruction effect.
Tilting/sloping of the document accommodating space can thus jeopardize
the desired result if no defacing agent/destruction agent has had time to
be distributed prior thereto.

[0005]One object of the present invention is to provide a method and an
arrangement which, when necessary, will provide particularly effective
defacing/destruction of items and articles stored in an alarmed valuable
article accommodating space regardless of the position to which the space
may be turned or of its orientation in space. This object is achieved
with a method and an arrangement having the characteristic features set
forth in the accompanying claims.

[0006]The advantages listed below are examples of the many advantages that
are afforded by the present invention.

[0007]The design and construction of the inventive arrangement are such as
to provide a very high degree of efficiency and will cause the
space-accommodated items to be marked/destroyed regardless of the
direction or attitude of the space, in other words regardless of the
rotational position of the space. For instance the arrangement will
function efficiently even when the space is turned upside down. No
gravitational effect is required for distributing the item
defacing/destroying agent.

[0008]A further significant benefit afforded by the invention is that the
space is diminished in conjunction with the distribution of the
defacing/destroying agent, meaning that the defacing agent/destroying
agent will be concentrated on the valuable items regardless of the
position to which the space is turned.

[0009]The use of an explosive device is not required and the inventive
arrangement is extremely service friendly. The inventive arrangement can
also be readily adapted to suit different types of value spaces.

[0011]The invention will now be described more specifically by way of
example and with reference to the accompanying drawings in which

[0012]FIG. 1 is a perspective view of a valuable document unit that
carries a staining unit;

[0013]FIG. 2 is a longitudinally sectioned view of the arrangement shown
in FIG. 1;

[0014]FIG. 3 is a perspective view of the staining unit;

[0015]FIG. 4 is a longitudinally sectioned view of the staining unit; and

[0016]FIG. 5 is a cross-sectioned view of the staining unit.

[0017]FIGS. 1 and 2 illustrate a valuable document accommodating unit 1
that comprises a reversibly rotatable drum 2, wherein valuable items, for
instance banknotes, can be wound onto and unwound from the drum with the
aid of foil strips/carrier films. The valuable items concerned are wound
onto the drum 2 by means of carrier film or foil 3,4 stored on reversibly
rotatable carrier rollers 5,6. As will be evident from FIG. 2, the
requisite control of the carrier films 3,4 is achieved by means of guide
rollers 11-19. As indicated by the arrow A, the valuable items/banknotes
are fed in between the carrier films 3,4 and wound onto the drum 2
together with the carrier films 3,4. The banknotes are discharged from
the drum 2, by reversing the direction of rotation of the drum 2 and the
rollers 5,6. A processor unit (not shown) is provided for monitoring,
controlling and steering the value unit 1.

[0018]The unit 1 includes a value space 30. The value space 30 is disposed
adjacent the drum 2 and is conforming generally to the shape of the drum
exterior and therewith restrict the volume of the space that is intended
to take-up a distributed defacing agent/destruction agent. The space 30
is delimited by a curved wall portion 31 and an angled wall portion 32.
Defined between said wall portions 31,32 is a gap 33 for passage of the
carrier films 3,4 and said banknotes to and from the drum 2. The value
space 30 is delimited sideways by walls of the value unit 1. The space 30
includes upwardly an opening for docking with a staining unit/defacing
unit/destruction unit 50.

[0019]As evident from FIGS. 1 and 2, the staining unit 50 can be connected
to and docked with the value unit 1.

[0020]The staining unit 50 has a box-like design and comprises a casing 60
whose bottom part includes an opening 61 through which defacing
agent/destruction agent is forced out into a value space. The staining
unit 50 has disposed in its bottom region two cutting blades 62,63 which
can be manoeuvred along the bottom surface of the casing 60 by means of a
cable or wire arrangement 64 and a tension spring 65, said cutters
functioning to puncture/slit when necessary a dye/colour container
provided in the staining unit 50. When the blades 62,63 are in an
inactive rest state, the blades are parked behind a blade guard 66 at the
same time as the tension spring 65 is fixed in an extended position.

[0021]The staining unit 50 includes in its upper region an agent
evacuating device 70 that includes a press plate 71 which is actuated by
a conical pressure spring 72. The press plate 71 is shown in its upper
end position in the figures, wherein the conical spring 72 is fixed in a
compressed state. The press plate 71 is therewith parked in its starting
position. The press plate 71 covers essentially the whole of the internal
space of the casing 60, as evident from the figures.

[0022]The staining unit 50 includes a circuit board 73 with requisite
electronic components, a power source 74 and an electric motor 75. The
electric motor 75 is designed to release the compressed fixation of the
pressure spring 72 and the withdrawn fixation of the tension spring 65
via a linkage system 76 in conjunction with an alarm. If desired, both
springs can be released simultaneously or in a given sequence and with a
chosen time displacement therebetween. It is beneficial, however, to
design the linkage system so that the conical pressure spring 72 will be
released somewhat prior to the release of the tension spring 65.

[0023]Furthermore, an alarm arrangement or an alarm system is adapted to
detect an unlawful attempt to manipulate and access the staining unit and
the valuable item unit.

[0024]When using the inventive arrangement the defacing/staining unit 50
and the valuable item containing unit 1 are mutually combined and docked.
Moreover the staining unit 50 is charged with, for instance, a dye C or a
defacing agent/destructive agent encapsulated in a plastic foil casing 80
or its like. The casing 80 enclosing the defacing agent is dimensioned to
adequately fill the empty space found in the casing 60 when the press
plate 71 is parked and fixated in its upper starting position. The foil
casing 80 is shown in chain lines in FIG. 5.

[0025]The following events take place in response to an alarm. The
electric motor 75 is activated so as to via the linkage system 76 cause
the release of the fixated and compressed pressure spring 72, wherewith
the spring is able to expand and move the press plate 71 for compression
of the foil casing 80. Also the fixated and extended tension spring 65 is
released via the linkage system 76, wherewith the tension spring 65 is
able to contract and via the cable or wire arrangement 64 cause the
blades 62,63 to move along the bottom surface of the casing 60 so as to
slit the foil casing 80, wherewith defacing dye/medium is ejected or
sprayed into the value space 30, therewith defacing or destroying the
valuable items present in said space. The pressure spring 72 is
dimensioned to provide a very powerful agent ejection at the same time as
it moves the press plate 71 to a terminal position E indicated in broken
lines in FIG. 5.

[0026]It will be understood that the inventive arrangement results in
satisfactory staining/defacing/destruction of the space-accommodated
items even when the arrangement is turned upside down. If for example the
unit containing the valuable items is turned upside down the powerful
ejection of staining fluid will effectively deface/destroy said valuable
items. The press plate 71 remains in its end position E when ejection of
the fluid is completed, thereby preventing fluid from running back into
the unit 50 while ensuring that the dye/colour/agent will remain in the
value space 30 so as to achieve a maximum defacing or destruction result.
The inventive arrangement will thus function satisfactorily in all
occurring working directions.

[0027]It will be understood that necessary seals are, of course, provided,
such as the seal 66.

[0028]Thus, a central feature of the present invention is that when an
alarm is triggered, the defacing agent/destruction agent will be
distributed in the value space at the same time as the combined volume of
the container 80 and the space 30 is reduced. This is made possible by
causing the press plate 71 to compress the container 80 and to keep the
container in its compressed state. Defacing agent/destructive agent C is
prevented from running back into the container 80 by the fact that the
communication opening between the container 80 and the space 30 will be
essentially blocked.

[0029]It will be understood that the structural design of the inventive
arrangement can be broadly varied within the scope of the inventive
concept. For instance, the puncturing element may have many different
forms.

[0030]It will also be understood that the inventive defacing arrangement
may be capable of co-acting with and of being adapted to suit many
different types of value spaces in addition to the space exemplified
above.

[0031]It will therefore also be understood that the invention is not
restricted to the illustrated and described arrangement and method and
that modifications can be made within the scope of the accompanying
claims.
